Leak Detection Aldgate
Hidden water leaks in Aldgate pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Aldgate buildings.
Local knowledge
Aldgate housing, from a leak engineer's side
Aldgate is a zone of transition, with renovated Victorian warehouses alongside new-build residential towers. This creates a clash of very old and very new plumbing systems, sometimes interconnected. The area is also a hub for incoming water mains, meaning pressure can be variable. In renovated warehouses, original cast-iron waste stacks are often retained, which can crack and leak internally. New builds may have underfloor heating systems where leaks are particularly difficult to locate.
Engineer's note
In Aldgate, old meets new in your plumbing. We're equipped to handle both, with rapid response to stop leaks in any system, at any hour.

What fails here
Common leak problems in Aldgate
01
Cast-iron stack failure
Original cast-iron soil stacks in converted warehouses can crack with age, leaking foul water inside walls. This is a severe health hazard. If you detect a foul smell or see brownish water staining, evacuate the area and call us for an emergency inspection and temporary bypass installation.
02
Underfloor heating leak location
New-build apartments often have underfloor heating pipes embedded in screed. A leak here causes localised damp and heat loss but is invisible. We use thermal cameras and gas tracer technology to pinpoint the exact loop and junction failure without tearing up the entire floor.
03
Variable pressure joint stress
As a mains hub, water pressure in Aldgate can fluctuate, stressing joints in both old and new pipework. This leads to sudden fitting failures. If you hear banging pipes or a joint lets go, turn off the main stopcock immediately and call us for a pressure assessment and repair.
04
Basement tank overflows
Many buildings here have old basement cold water storage tanks that feed upper floors. A ball valve failure can lead to continuous overflow and basement flooding. If you hear constant water running in a basement area, investigate safely and call us to repair or replace the faulty valve urgently.
Three methods, one marked point
Acoustic survey
Ground microphones and correlators follow the sound of escaping water through floors and ground.
Thermal imaging
Infrared cameras reveal wet patches and buried heating runs through the floor surface.
Tracer gas
A safe hydrogen mix escapes through the exact failure point and rises to our surface detector.
Leak detection in Aldgate — FAQs
How quickly can you attend a leak in Aldgate?
Same-day appointments are usually available in Aldgate and across City of London, and next-day almost always. If water is actively escaping, say so when you book — live leaks are prioritised and we can talk you through isolating the supply while the engineer travels.
What does leak detection cost in Aldgate?
A fixed fee agreed at booking — typically £250–£450 for a domestic detection visit — covered by no find, no fee. That includes pressure testing per circuit, thermal imaging, acoustic survey and moisture mapping. Repairs are quoted separately before any work starts.
Do you know Aldgate properties?
Yes — Aldgate is a zone of transition, with renovated Victorian warehouses alongside new-build residential towers. This creates a clash of very old and very new plumbing systems, sometimes interconnected. The area is also a hub for incoming water mains, meaning pressure can be variable. In renovated warehouses, original cast-iron waste stacks are often retained, which can crack and leak internally. New builds may have underfloor heating systems where leaks are particularly difficult to locate.
Can you provide a report for my insurer?
Every Aldgate detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
